* feat(7642): bin/compactStalePads — staleness-gated bulk compaction
Adds bin/compactStalePads with --older-than / --keep / --dry-run.
Composes listAllPads → getLastEdited → compactPad so hot pads in
active timeslider use are left alone and only the cold tail is
compacted. Targeting stays a CLI concern; compactPad's API surface
is unchanged.
Per-pad failures (including a getLastEdited fault) don't stop the
run — same error-tolerance shape as compactAllPads. End-to-end test
plumbs through the real /api/1.3.1/getLastEdited + compactPad
endpoints to lock the adapter contract.
Daily-cron variant (cleanup.compactOlderThanDays setting) deferred
to a follow-up so this PR stays focused on the on-demand operator
tool from the issue's primary acceptance bullet.

* fix(7642): TOCTOU recheck before compaction + admin CLI docs
Qodo flagged two real issues:
1. Race window between staleness selection and compaction. On a long
bulk run a pad could become active between first-pass filtering and
compactPad, which would then kick those sessions. Added a getLastEdited
recheck right before each compact call; if the pad is now fresh it's
reclassified as skippedFresh rather than failed (the user did the
right thing — edited it — and we bow out).
2. doc/cli.md had nothing on pad compaction at all (gap predates this
PR; #6194 landed without doc updates). Added a Pad compaction section
covering all three CLIs — compactPad, compactAllPads, compactStalePads
— so the toolset is discoverable as a unit.
Tests cover both the recheck-skip path and a recheck-failure path.
